Title: Procede de production de lames de bois concues pour etre transformees en bois d'oeuvre composite
Inventor: SELBY JOHN S
IPC: B27L5/06
Filed: 1998-06-04
Granted: 2005-03-29
Abstract: Cette invention se rapporte à un procédé servant à produire des planches (12) à partir de rondins de bois façonnés (2), à la fabrication de lames ou de lattes de bois (20) à partir de ces planches (12) et à des procédés d'assemblage de ces lames pour former du bois d'oeuvre composite. Ce procédé se fonde en partie sur le principe de la préparation de planches (12) qui conservent la voussure ou la courbure longitudinale naturelle du rondin et d'un tronçonnage qui suit la voussure des rondins, pour permettre la préparation de lattes (20) destinées à être transformées ensuite en bois d'oeuvre composite. A cet effet, on pratique dans le rondin (2) une découpe d'ouverture (4) qui suit essentiellement la courbure de la voussure du rondin ou qui est parallèle à cette courbure, afin de diviser le rondin en deux pièces de volume approximativement égal. Les surfaces opposées (14) sont usinées parallèlement à la surface formée par la découpe d'ouverture, de manière à produire une planche. On coupe ensuite ces planches (12) en suivant la courbure de la voussure, afin de produire des lattes (20). La surface naturelle du rondin est de préférence préservée sur les côtés des planches. Les lattes peuvent ensuite être équarries et assemblées par collage de différentes manières, pour produire du bois d'oeuvre. Ce procédé permet d'obtenir à partir de rondins bruts un rendement particulièrement élevé de bois d'oeuvre ayant le même aspect extérieur, les mêmes propriétés et la même facilité d'utilisation que du bois d'oeuvre scié plein.

Title: Burner with piloting ports
Inventor: JENNINGS RALPH ERNEST
IPC: F23D14/26
Filed: 2000-03-23
Granted: 2008-11-18
Abstract: A cooking appliance includes burners having ports that are aligned in a defined alignment with respect to an adjacent structure of a burner body or the cooking appliance within a piloting zone so that the adjacent structure guides the formation of a flame kernel at an outlet of the port. The adjacent structure may be ports which also form flame kernels withing the piloting zone of the burner port outlet, a structural portion of the burner body such as an extended lip protruding beyond the burner port or a separate structure such as a flame rod or other target that stabilizes the flame kernels at the burner port outlet. Such structures provide a method for improving the turndown ratio of burners by preventing lifting or backlash of the flame kernels generated at the burner port outlets by aligning the ports in conjunction with an adjacent structure within a piloting zone.

Abstract: A method is provided for testing prestressed concrete pipe (12). 1n the method, elastic waves are serially induced at least three different inducing locations along the surface of the conduit. The shear wave (5) component of each induced elastic wave is detected by at least one, and preferably two, acoustic sensors (16) disposed at fixed sensing sites (17) along the conduit (12). The relationship between at least one parameter of each induced shear wave and the distance between each inducing location (15) and the acoustic sensors} (16), are correlated and compared with standard correlations to identify structural discontinuities in the conduit (12). In a typical example of the method, elastic waves are induced using a mechanical hammer (18) at multiple inducing sites (15) around a multiplicity of annuli along the length of the conduit. Each annulus is separated from adjoining annuli by 2-4 feet.

Title: Method and apparatus for determining logging tool displacements
Inventor: FREEDMAN ROBERT
IPC: E21B47/022
Filed: 2000-06-30
Granted: 2006-06-06
Abstract: A method of determining the displacements of a logging tool during a measurement interval of the logging tool in a borehole includes obtaining a set of accelerometer signals corresponding to accelerations of the logging tool along each of three orthogonal axes of the logging tool during the measurement interval. The method further includes calculating a lower bound for the displacements of the logging tool during the measurement interval when the initial velocity and the gravitational acceleration are unknown. The lower bound on the displacements of the logging tool is used to flag the validity of the measurements made by the logging tool.

Abstract: A data animation program (11) is provided that alters the appearance of an animated object (39) to reflect a per-centage change in data represented by the animated object. The data is pro-vided to the data animation program by a data source (20) such as a tempera-ture sensor or an Internet web site. The percentage change in data is converted to a rate of motion for the animated ob-ject. The appearance of the animated object is then altered in accordance with the rate of motion. For example, if the animated object is a propeller, the rate of motion will be expressed in revolu-tions per minute (RPMs) and the pro-peller then spins at the determined rate of motion so as to indicate the percent-age change in data represented by the animated object.

Title: Odd-transform fast convolution
Inventor: HELLBERG LARS RICHARD BIRGER
IPC: G06F17/14
Filed: 1999-09-24
Granted: 2012-04-10
Abstract: The present invention relates generally to the problem of filtering, decimation or interpolation and frequency conversion in the digital domain, and more particularly to the use of the stand-alone or improved modified fast convolution algorithm in wideband multichannel receiver, channelization, and transmitter, de-channelization structures of a radio communication system. The invention consists of essentially 3 steps: making sure that we use different overlaps on consecutive blocks that, on average, give the same overlap on both the input and output ends; aligning the signal in consecutive blocks of time;  and compensating for phase shifts due to frequency shifting. The essence of the invention is that it decouples the input and output transform lengths in the fast convolution algorithm from each other and from the overlap, making it possible to use any transform length on the input together with any transform length on the output and at the same time use any overlap. This provides an enormous amount of freedom compared with the limitations of state of the art.
